A stochastic hybrid model with a fast concentration bias for chemotactic cellular attraction
Ojer Ferrer, Jaume; García López, Alvaro; Used, Javier; Fernández Sanjuan, Miguel Angel (2022-03)
Article
Accés obertWe reproduce the phenomenon of chemotaxis through a hybrid random walk model in two dimensions on a lattice. The dynamics of the chemoattractant is modelled using a partial differential equation, which reproduces its ... -
Flocking dynamics mediated by weighted social networks
Ojer Ferrer, Jaume; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2022-10-03)
Article
Accés restringit per política de l'editorialWe study the effects of animal social networks with a weighted pattern of interactions on the flocking transition exhibited by models of self-organized collective motion. We consider variations of traditional models of ... -
Modeling explosive opinion depolarization in interdependent topics
Ojer Ferrer, Jaume; Starnini, Michele; Pastor Satorras, Romualdo (American Institute of Physics (AIP), 2023-05-17)
Article
Accés obertUnderstanding the dynamics of opinion depolarization is pivotal to reducing the political divide in our society. We propose an opinion dynamics model, which we name the social compass model, for interdependent topics ...
